How to set edgesForExtendedLayout to none in Swift 3

The problem is that my View, containing a `UIView` and a `UITableView` within a `ScrollView`, gets hidden under the `UINavigationBar` if set translucent. I have considered several threads like this, but they all suggest to set: ``` self.edgesForExtendedLayout = UIRectEdgeNone ``` In Swift 2, this code was: ``` self.edgesForExtendedLayout = .None ``` I have updated to Xcode 8.1 and Swift 3.0.1 today, but I can't find anything in the release notes about this matter. The compiler tells me, that `.None` got changed to `.none`, but after edit, that `.none` does not exist. Changing it to `.top` did not had any effect. The tableView is setup programatically and putting `insets` does not help because I have a `scrollView` with a `UIView` on top of the `UITableView` that is hidden under the `UINavigationBar`. What am I missing? Help is very appreciated.
